New Freshwater Crab Species Unearthed in Kerala’s Western Ghats

quick Summary

• researchers at the Department of Aquatics Biology and Fisheries, University of Kerala, discovered a new genus and two new species of freshwater crabs in the Western Ghats.
• The new genus, Kasargodia sheebae, was found in Ranipuram Hill Station, Kasaragod district. It features a brownish-orange carapace with black spots.
• Another species, Pilarta vaman, named after an avatar of Vishnu for its small size, was found in Gavi, Pathanamthitta district. It has a quadrate carapace.
• Both findings were published in scientific journals: kasargodia sheebae in the Journal of Crustacean Biology and Pilarta vaman in Zootaxa.
• Researchers noted that freshwater crab diversity in the Western Ghats is largely unknown due to their secretive nature and nocturnal habits.
• Endemism for freshwater crabs in Kerala’s Western Ghats is high (about 70%), but habitats face threats from anthropogenic activities such as tourism.

Indian Opinion Analysis

The finding highlights India’s rich biodiversity within the ecologically sensitive Western Ghats region. With close to 70% endemism among freshwater crabs here, it underscores how these areas serve as critical reservoirs for unique wildlife forms. However, challenges such as habitat degradation due to tourism pose potential risks to these endemic species. Addressing this requires balancing conservation efforts with sustainable development strategies to ensure protection while promoting eco-tourism responsibly.Scientific advancements like these underline India’s need for continued study and management of its natural heritage.Read more
